For Windows: On FF, this looks somewhat jerky as you mentioned, and very smooth in Chrome. Opera surprised me negatively: On some of the animations, the horizontal/vertical movement didn't happen at all (on e.g. Nervous Horizontal and Vertical Wobbling). Safari amazed me: Worked just as good as Chrome. Internet Explorer 9 worked amazingly well too: the movement worked okay from what I saw, the only error I could see this time was no round edges. And for the loading times: Chrome and Opera fastest, then Safari, Firefox and last: Internet Explorer. Nothing surprising here.
